As a police officer, technology helps me work safely and more efficiently.In the UK, not all police officers are licensed to carry firearms-guns and so on - but all of us have batons.We all have handcuffs-still the simplest way to restrain someone.And we wear knife-proof vests, a kind of body armour made of Kevlar.Some police forces are experimenting with stun guns, tasers, for use against suspects armed with a dangerous weapon, like a knife.We also have CS gas canisters.If someone gets violent, CS will incapacitate them for a short time.We all carry radios so we can contact each other and police headquarters at any time.For example, we all carry a torch.It's lightweight and metal, so not easily broken.
